Yield stability is fundamental to global food security in the face of climate change, and better strategies are needed for buffering crop yields against increased weather variability. Regional- scale analyses yield can support robust inferences about widely-grown staple crops, but have not been accomplished. We present a novel analytical approach, synthesizing 2000-2014 data on soil factors quantify their impact county-level maize four US states that vary widely these (Illinois, Michigan,...

Wild bees, like many other taxa, are threatened by land-use and climate change, which, in turn, jeopardizes pollination of crops wild plants. Understanding how factors interact is critical to predicting managing pollinator populations ensuring adequate services, but most studies have evaluated either or effects, not both. Furthermore, bee species incredibly variable, spanning an array behavioral, physiological, life-history traits that can increase decrease resilience change. Thus, there...

Abstract The pollination services provided by bees are essential for supporting natural and agricultural ecosystems. However, bee population declines have been documented across the world. Many of factors known to undermine health (e.g., poor nutrition) can decrease immunocompetence and, thereby, increase bees’ susceptibility diseases. Given myriad stressors that exacerbate disease in wild populations, assessments relative impact landscape habitat conditions on pathogen prevalence needed...

Climate models predict increasing weather variability, with negative consequences for crop production. Conservation agriculture (CA) may enhance climate resilience by generating certain soil improvements. However, the rate at which these improvements accrue is unclear, and some evidence suggests CA can lower yields relative to conventional systems unless all three elements are implemented: reduced tillage, sustained cover, rotational diversity. These cost-benefit issues important...

Wild pollinators supply essential, historically undervalued pollination services to crops and other flowering plant communities with great potential ensure agricultural production against the loss of heavily relied upon managed pollinators. Local provision wild bees crucial floral nesting resources, but distribution floristic diversity among habitat types in North American landscapes its effect on are diverse poorly understood, especially orchard systems. We documented typical mid-Atlantic...

Abstract Wild and managed pollinators are essential to food production the function of natural ecosystems; however, their populations threatened by multiple stressors including pesticide use. Because pollinator species can travel hundreds thousands meters forage, recent research has stressed importance evaluating decline at landscape scale. However, scientists’ conservationists’ ability do this been limited a lack accessible data on use relevant spatial scales in toxicological units...

Introduction There is overwhelming evidence of declines in native bee populations and therefore a need for increased monitoring to track these assist conservation restoration efforts. Bees can be sampled non-lethally through visual surveys (e.g., distance transects) or lethally active hand netting) passive traps that lure insects from afar) methods. These lethal methods suffer imperfect detection difficult account confound inferences about habitat characteristics. Additionally, suggests...

Cover cropping is a conservation practice that has captured the enthusiasm of farmers and professionals alike over past decade. The practice, planting crops primarily “to manage soil fertility, quality, water, weeds, pests, diseases, or wildlife,” (USDA NASS 2012) grown in popularity last 10 years to level not seen since advent widespread adoption synthetic fertilizers following WWII (Craven 1926; White 2015; Magdoff Van Es 2009). Many federal agencies farming environmental stewardship...

Abstract Managed honey bee (Apis mellifera L.) colonies in North America and Europe have experienced high losses recent years, which been linked to weather conditions, lack of quality forage, parasite loads, particularly the obligate brood parasite, Varroa destructor. These factors may interact at various scales compounding effects on health, but few studies able simultaneously investigate landscape factors, management parasites. We analyzed a dataset 3,210 survey responses from beekeepers...

Abstract Due to the key role surrounding landscape plays in ecological processes, a detailed characterization of land cover is critical for researchers and conservation practitioners. Unfortunately, United States, data are split across thematic datasets that emphasize agricultural or natural vegetation, but not both. To address this gap, we merged two datasets, LANDFIRE National Vegetation Classification (NVC) USDA-NASS Cropland Data Layer (CDL), produce integrated ‘Spatial Products...

Abstract With documented global declines in insects, including wild bees, there has been increasing interest developing and expanding insect monitoring programs. Our objective here was to organize, validate, share an analysis-ready version of one the few existing long-term datasets for bees United States. Since 1999, Native Bee Inventory Monitoring Lab (BIML) States Geological Survey sampled wild-bee communities Mid-Atlantic U.S., but samples were collected multiple studies are not fully...

As insect populations decline in many regions, conservation biologists are increasingly tasked with identifying factors that threaten species and developing effective strategies for their conservation. One group of global concern fireflies (Coleoptera: Lampyridae). Although quantitative data on firefly lacking most species, anecdotal reports suggest some have declined recent decades. Researchers hypothesized North American threatened by habitat loss, pesticide use, light pollution, but the...
